To all whom it may concern:

Be it known that I, Jnrrin W. Hairpin, a citizen of the United States,and a resident of Sourlake, in the county of Hardin and State of Texas,have made certain new and useful Improvements in ater-Heaters, of whichthe following is a specification.

My invention relates to improvements in feed water heaters and has forits object to provide an improved apparatus for the rapid and economicalheating of water for steam purposes in oil and gas burning boilers.

My invention consists in certain novel tca tures of construction,arrangement and combination of parts as will be hereinafter fullydescribed and pointed out in the claims, reference being had to theaccompanying drawings, in which Figure 1. is a perspective view of aboiler turnace showing location of my improvement. Fig. 2 is a rear Viewof the tar et Fig. 3 a section taken on line S-3 ot Fig. Fig. 4 is asection taken on line d4; of

In carrying out my invention I use a plate A of cast iron, which may besquare or oblong and may be from one-halt to one inch in thickness, thisplate being termed the target This plate is set up inside the boilerturnacc in place of the tire brick target used in oil burning boilers.To the back of the target is secured the pocket 1%, which, as shown, isenlarged at its central portion 3* and narrows down toward its endswhere the connections for the feed water pipe are made. The incomingteed water enters the pocket B at end B and after passing diagonallyacross the target, that being the position of the pocket, discharges atthe end B that is, the water from the teed pipe on its way to the boilerteed connections will pass immediately back of the target plate andthrough the pocket, passing directly opposite and back of the pointwhere the jet of burning fuel oil is thrown against the plate. Thepocket B will be appr Ximately three times the capacity of the samelength of straight teed pipe, thus permitting the water to pass slowlyby the point where the fire is hottest, thus becoming already heatedbefore it reaches the boiler teed connections. The base of the targetplate is made with. a flange B extending rearwardly and bent at such anangle that the target plate stands at an angle of about by thusinclining the target plate backward the heat thrown against the targetplate from the oil jet is deflected upward and toward the boiler dues,and thus avoiding waste of heat. in the event it is desired to use morethan one boiler, or, what is known as a battery of boilers, these platesor targets may be connectcd by the teed pipe, and, the water instead ofpassing from the first target or heating pointinto the first boiler,will pass through the heat. of all the boilers in the battery. and isfed back hot into the other boilers by means of ordinary teed lines orfeed columns, thus greatly reducing the amount of i'uel oil or gasrequired tor producing the necessary amount of steam. These targets maybe made in any desired size, for use in connection with the varioussizes and kinds of boilers used.

The front of the target. will be protected by a facing of the brick orother heat resisting medium, held thereon in any suitable manner. Thetarget plate may be made in sections which can be readily passed throughthe furnace door, and then assembled and held together in a. singleplate by tongues and'grooyes, or other suitable means. The target itselfmay constitute the circulating medium for the feed water, it only beingnecessary that such medium shall be interposed in the path ot theinjected flame. The flange B may also be dispensed with as the feedwater pipe connections will form a suitiiciently strong support tomaintain the target in its desired position. By inclining the target thefull force of the flame is not allowed to get to the boiling lines assuch would soon burn them out.

i: claim l. A device for heating feed water in oil or gas burning boilerfurnaces, consisting of a target plate mounted within the lire box andinclined upwardly and rearwa-rdly in the tire box, a pocket located atthe rear of said plate, said pocket having connection at one end withfeed supply, and at the other end with the boiler teed connections.

2. A device for heating teed water in oil or gas burnin boiler furnaces,consisting of target plate having a bent base to cause the plate tosetat an angle and project upwardly and rcarwardly in the fire box, a

pocket located at the back of the plate to serve as a passage for feedwater, said pocket being enlarged in its central portion, and havingconnection at one end with the feet water supply and at the other withthe boiler feed connections.

3. A device for heating feed water in oil or gas burning boilerfurnaces, consisting oi? a target plate having a flanged base disposedatan angle to cause the plate to suine a rearwardly inclined position, apocket located at the back of the plate and extending diagonally acrossthe same, said pocket serving as a passage for feed water and having aconnection at one end with the feed water supply and at its other endwith the boiler teed connections.

t. A device for heating feed water in oil or gas burning boilerfurnaces, consisting ot a metal plate having anangularly disposed baseflange, a pocket placed at the back of said plate extending diagonallyacross the same, and having its central Zone enlarged, said pocketserving as apassage for the teed water, and having connection at one endwith the feed water supply, and at its other end with the boiler teedconnections.

5. A device for heating teed water in oil or gas burning furnaces,consisting of a feed water conducting medium located within the fire boxand tilted rearwardly at an angle from the vertical, and positioned toreceive and defiect upwardly and rearwardly the flame of an injectorburner.

(3. A device for heating feed water in oil or gas burning furnaces,consisting of a target plate constituting feed water medium, tiltedrearwardly at an angle from the Vertical, and positioned in the fire boxof the furnace to intercept and deflect upwardly and rearwardly theflame of an injector burner.

T. A device for heating feed water in oil or gas burning furnacesconsisting of a target plate placed within the fire box of the furnaceand inclined upwardly and rearwardly, a pocket forming part of saidplate and having connection at one end with the feed water supply and atthe other end with the boiler teed connection, said feed water andboiler feed connections supporting and holding the target plate inposition within the fire box.

8. A device of the class described comprising an oil discharge nozzle, atargetin the path thereof and constituting a feed water heater, andmeans for directing water to and from the target.
